A buddy of mine has a old rifle with some imprinting near the reciever on the barrel that looks like chinese or Japenese ( I don't know). It is a hammer with a rolling block in front of the hammer. Appears to be about a .45 cal. Just looking to see what it is and what it might be worth. Not sure how to post pictures, here is my email if that works to email them. Thanks, Steve Tido4570@yahoo.com
